Abstract
Abstract A reservoir for a bobbin changer for cigarette paper or a similar paper web includes, adjacent to an inlet (15) at which the paper (10) enters the reservoir, a movable deflector (20) arranged to engage and deflect the paper as it enters the reservoir (at least while paper is being accumulated in the reservoir) and to promote folding of the paper into loops in which the paper can safely be stored in the reservoir. The deflector is preferably pivoted and is arranged to be pushed away from the inlet by the accumulating loops of paper until the deflector reaches a nearly vertical position whereupon the bunched up loops of paper drop into the reservoir.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
87 words
A reservoir for a bobbin changer for cigarette paper or a similar paper web including, adjacent to an inlet at which the paper enters the reservoir, a deflector which is mounted in the reservoir for movement toward and away from the inlet and is arranged to engage and deflect the paper as it enters the reservoir, at least while paper is being accumulated in the reservoir, and to promote the folding of the paper into loops in which the paper can safely be stored in the reservoir.
Claim 2
Dependent Claim
87 words
A reservoir for a bobbin changer for cigarette paper or a similar paper web including, adjacent to an inlet at which the paper enters the reservoir, a deflector which is mounted in the reservoir for movement toward and away from the inlet and is arranged to engage and deflect the paper as it enters the reservoir, at least while paper is being accumulated in the reservoir, and to promote the folding of the paper into loops in which the paper can safely be stored in the reservoir.
Claim 3
Dependent Claim
29 words
A reservoir according to claim 1 in which the deflector is arranged to move progressively away from the paper inlet under the pressure of the accumulated loops of paper.
Claim 4
Dependent Claim
13 words
A reservoir according to claim 2 in which the deflector is pivotally mounted.
Claim 5
Dependent Claim
29 words
A reservoir according to claim 2 in which movement of the deflector under the influence of pressure from the accumulated loops of paper is resisted by a restraining force.
Claim 6
Dependent Claim
21 words
A reservoir according to claim 4 in which the restraining force is provided by a balance weight mounted on the deflector.
Claim 7
Dependent Claim
41 words
A reservoir according to claim 1 in which the normal path of the paper through the reservoir is such that the paper engages the deflector and, as a result of tension in the paper, holds the deflector away from the inlet.
Claim 8
Dependent Claim
144 words
A reservoir for a bobbin changer for cigarette paper or a similar paper web including, adjacent to an inlet at which the paper enters the reservoir, a movable deflector arranged to engage and deflect the paper as it enters the reservoir, at least while paper is being accumulated in the reservoir, and to promote folding of the paper into loops in which the paper can safely be stored in the reservoir, and a paper tension sensing arrangement for controlling the speed of a roller feeding paper into the reservoir and comprising a vertically movable false inner wall arranged to rest on the paper in the reservoir and to control the roller speed in response to the position of the wall, the wall also serving to separate, from the paper leaving the reservoir during a bobbin changing operation, the looped paper accumulated in the reservoir.
Claim 9
Dependent Claim
144 words
A reservoir for a bobbin changer for cigarette paper or a similar paper web including, adjacent to an inlet at which the paper enters the reservoir, a movable deflector arranged to engage and deflect the paper as it enters the reservoir, at least while paper is being accumulated in the reservoir, and to promote folding of the paper into loops in which the paper can safely be stored in the reservoir, and a paper tension sensing arrangement for controlling the speed of a roller feeding paper into the reservoir and comprising a vertically movable false inner wall arranged to rest on the paper in the reservoir and to control the roller speed in response to the position of the wall, the wall also serving to separate, from the paper leaving the reservoir during a bobbin changing operation, the looped paper accumulated in the reservoir.
Claim 10
Dependent Claim
87 words
A reservoir for a bobbin changer for cigarette paper or a similar paper web including a paper tension sensing arrangement for controlling the speed of a roller feeding paper into the reservoir and comprising a vertically movable false inner wall arranged to rest on the paper in the reservoir and to control the roller speed in response to the position of the wall, the wall also serving to separate, from the paper leaving the reservoir during a bobbin changing operation, the looped paper accumulated in the reservoir.
Claim 11
Dependent Claim
87 words
A reservoir for a bobbin changer for cigarette paper or a similar paper web including a paper tension sensing arrangement for controlling the speed of a roller feeding paper into the reservoir and comprising a vertically movable false inner wall arranged to rest on the paper in the reservoir and to control the roller speed in response to the position of the wall, the wall also serving to separate, from the paper leaving the reservoir during a bobbin changing operation, the looped paper accumulated in the reservoir.
